I’m no science guy, so I’m not quite sure what the full extent of this fruit’s power would be. I just thought a plasma logia would be cool.

The Taieki Taieki no Mi (English: Plasma Plasma Fruit) is a logia type devil fruit that grants its user the ability to manipulate, create, and become plasma at will.

Strengths: 
Aside from the usual intangibility provided by most logia type fruits, the greatest strength of the Taieki Taieki no Mi is it’s ability to allow its user to control electricity to a certain extent. Using a large battery attached to his back, the user of the fruit, Marlo, is able to electrify his highly conductive plasma, using it to electrocute opponents as well as line the battlefield in hazardous electrified plasma.

Weaknesses:
Outside of its ability to conduct and harness electricity, the Taieki Taieki no Mi has few offensive uses. Taking away access to electricity will make the fruit relatively harmless. 

Awakening:
Upon awakening their fruit, the user of the Taeki Taeki no Mi can generate up to 6.3kWh of electricity that can be either conducted through their plasma or simply shot straight at foes. The user's plasma is also now effectively 5 times as conductive as it was before.

Special Techniques: 

Wattlop: the user launches a wave of electrified plasma at foes

Plasma Twister: the user forms giant plasma twisters and electrifies them

Shock Palm: the user forces their electrified plasma covered palm into an opponent

Plasma Shot: the user shoots a beam of concentrated plasma from anywhere on their body. This beam can be electrified. 

Plasma Rain: the user rains down concentrated plasma bullets on foes. These bullets can also be electrified. 

Awakened techniques are just the special techniques but without the need for a power source and much more potent.
